On prior cars I've used Accutint Seattle (expensive) and Darkside Tinting on Lake City Way (cheap but well done). I'm thinking about 40-50% tint for heat control and would try Accutint NW on Aurora. I had them detail a car once and was impressed with price, service, and a great detail. I think $450 is pricey but it depends on the film too. I would probably max out at $400.
